Hi,
I've started with random selection of parts just to start making it simply
Do you think it´s a good idea to start with 3 eggs and 50g of wheat to bake a cake?
Or do you think it´s better to first decide
which cake you want to bake, then look for an suitable
receipt?
Note: a "simple" circuit" may work as phase control for a (resistive) heating. But to control an (inductive) AC motor isn´t that simple
(it´s not that difficult either). You just have to take care about the
& yes alot of circuits on the internet but it seems no one is working good &
How do you know they are not working good?
True, random internet search gives a lot of unreliable designs. Thus I recommeded to look at the
semiconductor manufacturers. They earn their money to sell their devices. But no one will buy the devices if the datasheet is faulty or the application notes are faulty...--> they are interested in giving reliably working designs.
i have downloaded the Moc3021 datasheet but no clear information about its output regarding to its input
From function the datasheets says you need typically 8mA LED current to trigger the output = trigger the triac.
It´s a
digital input and it´s a trigger output, that´s all.
It´s
not the job of the MOC to control the phase angle. This is the job of the microcontroller (code)..
But theses are basics you already should know before you think about using "BT136"...
BTW:A forum cant replace school and can´t replace reading tutorials, books, application notes, datasheets,
And there are a lot of video tutorials about AC motor phase control.
